Openalpr: License Plate not found

Created on 4 Oct 2017  路  8Comments  路  Source: openalpr/openalpr

I'm new to openalpr and I have to use openalpr for detecting Indian number plates. But when i run any image file with country code as in(india), it throws an error of "License Plate not found" I have used the new openalpr repository that has trained data for indian number plates. But I'm not able to use it. Could you tell me what I'm doing wrong.

Same thing for me as well.
Images that work in the cloud api do not work on the CLI tool.
I have even tried the 'demo' image of the github page and it still says 'No license plates found'

Other images i have tried and i still get the same error:
1, 2, 3, 4

Again these images work on the cloud api.

PS) I am using the precompiled Windows binaries

I can confirm this issue and would like to bump up this issue.

Of the images I tried, while the cloud api is able to recognize the number plates, I do not see the command line tool do the same.

Hi All,
I've tried it on Linux as well. I don't run into any errors. The lin.traineddata, in.conf and in.xml files are all available as well. I still get a no numberplate detected. Even tweaking the Indian configs doesn't give any result.
The API seems to work though like how everyone has mentioned.

Any help on this ?

Can you please provide the image

Did you try changing the country code. For india it is -c in. By default it is 'eu'

Same here I've tried openalpr on docker the installation was successful and the image on the installation guide works fine but I just get 'No license plates found' for any other images but the cloud API works fine for those same images.

Has this issue been resolved? I gave "in" in the country settings, yet getting number plate not found.
